Here, the boy found not only a bunch of antique artifacts, but also his grandfather’s diary. It turned out that Professor Aurelius had been studying… magic! He desperately wanted to unravel the secret of the magic sphere—a magical artifact possessing immense power. And now Alex has to continue his work! After all, this is the only way to find his grandfather. But what dangers await him along the way?
